What is the origin of geomantic omen in green house?

Yang Junsong thinks that the whole basin is like a huge compass, the stone peak in the middle is like a pointer, and pine trees and boulders are like Mr. Feng Shui's umbrella and bag. This kind of terrain is naturally very suitable for Mr. Feng Shui to live for generations. So, he and his disciples Zeng Wenzhou and Liao Li each built a hut, forming the earliest "Sanliao Village", which was named only in the late Tang Dynasty, but Qingwuzi did not have this "Sanliao Village" at that time.
